Tags and values for Resource Groups from a CSV

Hi Guys! I am quite a newbie using PowerShell, and I am in need of a little assistance. Currently I am using PowerShell for Azure, and I need to import data from a CSV file to Azure. The details are Tags, values of tags, and Resource Groups. I have tried searching for this on the interwebs, but no such luck. I'm not sure of what other details you may need, but let me know if I am missing anything.
Thanks again!

Well, I guess, let's start with what you've already tried. For example, do you know how to import the CSV file? Do you have an idea of the process you want, and just don't know the commands you'd need? What's the job task, here – digging up existing resources and tagging them, creating new resources, something else? I'm not sure you really just 'import data into Azure' unless it's just going into a database – which also might be what you're after...?

Hi Don!
So what is happening here is this. Some of our DevOps guys have a DEV subscription with resource groups already in play. They want the current resource groups renamed and then have 4 tags with variables for each tag applied.

Ah. Yeah, I'm insufficiently Azure-savvy to tell you how to rename resource groups. But, I'd probably just read in the CSV, enumerate each line, and do whatever command is needed to rename, assuming one exists.
